The Planning (Amendment) Bill seeks to strengthen the Urban Redevelopment Authority's (URA) powers to regulate urban development and ensure a liveable city. It introduces stricter penalties for planning violations, including custodial sentences for repeat offenders and those involved in unauthorized dormitory use. The bill also mandates the appointment of Qualified Persons to oversee development plans and enhances URA's investigation powers. Additionally, it legislates new rules to cap subletting of private properties to six unrelated persons and prohibits short-term rentals of less than six months without permission. Stakeholders have raised concerns about the alignment of rules for HDB flats, the clarity of due diligence requirements for property owners, and the implementation of design guidelines that may affect development costs.
